Abstract

Abstract:

The development of shale gas resources in China has been in full swing and accessed to strategic breakthroughs which effectively alleviated the contradiction between the demand and supply of clean energy. However, shale formation instability was still a technical difficulty in the operation of drilling fluids. Micro-nano particles received wide attention because it can effectively plug micro-pores in shale formations. In this paper, the importance of micro-nano plugging agent for the stability of shale gas wells was analyzed. The evaluation methods, mechanism, research and application status of micro-nano plugging agents were also discussed. From the point of the interaction between the treating agent and the clay minerals, the research and development of micro-nano plugging agent was put forward. Finally, evaluation medium and methods of micro-nano particles methods were also put forward.

Key words: Shale gas, Wellbore stability, Micro, nano particles

摘要： 我国页岩气资源开发已经全面展开并获得战略性突破,有效地缓解了清洁能源需求与供给间的矛盾。但页岩地层井壁失稳仍然是钻井液施工过程中的技术难点,能够高效封堵页岩地层微孔隙的微-纳米粒子材料受到广泛关注。分析了微-纳米封堵剂对于页岩气井壁稳定的重要性,论述了目前微-纳米封堵剂的评价方法、作用机理、研究及应用现状和存在问题。从处理剂与地层黏土矿物间作用力的角度出发,提出微-纳米封堵剂的研发思路。最后,提出微-纳米粒子评价介质和手段的改进方法。

关键词: 页岩气开发, 井壁稳定, 微-纳米封堵剂
